DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENTS

In various embodiments, the present invention comprises a system forquickly and easily interchanging various furniture bases with variousfurniture seats or seat boxes by means of an interlocking connection,such as a multi-part cam assembly. A furniture base can be quickly andeasily detached from a particular seat box, and replaced by a differentstyle of furniture base. The present system suitable for all furniture,reclining or non-reclining, where connection is desired, such as, butnot limited to, sofas, loveseats, chairs, sectional pieces, ottomans,rockers, gliders, swivels, swivel rocker, sleepers, and the like, eachwith their respective seat boxes and bases. The present invention allowsthe furniture seat boxes and bases to be disconnected and connected invarious combinations as desired, by the consumer, the retail store, orothers, as described above.

FIGS. 30-53 shows detailed views of various furniture bases 510, 520,530, 540, 550, 560 with a two-piece cam assembly 500 (examples of whichare described below) in place. The lower piece of the cam assembly isaffixed or fastened to the respective bases as shown (e.g., fixed base510, glider base 520, rocker base 530, stationary swivel base 540,swivel glider base 550, swivel rocker base 560), while the upper pieceof the cam assembly, which is shown in interlocking position with thelower piece of the cam assembly, is affixed or fastened to the seat boxor seat or upper furniture component (as seen in FIG. 1A). A base isdetached from the seat box or seat or upper furniture component bydisengaging the pieces of the cam assembly from each other. Areplacement base, with its own pair of cam assembly lower pieces, ispositioned to align the lower pieces with the upper pieces on the seatbox or seat or upper furniture component, and then pushed together tointerlockingly connect. In several embodiments, the interlockingconnections are designed so all bases have lower cam pieces that caninterlock with all corresponding upper cam pieces on all seat boxes,seats or upper furniture components.

In several embodiments, the present invention enables a glider base (invarious forms) to be attached to a rocker scissor mechanism attached toa seat box or seat. This avoids the requirement for a glider sideassembly mechanism to be separately attached to the scissor mechanism,as is the case with prior art rocker gliders. The present invention thusallows a rocker to be converted to a rocker-glider or a glider withoutthe need of a separate glider side assembly mechanism, thereby reducingparts and costs.

In several further embodiments, two or more cross tubes extend laterallybetween the two sides of the bases (in the embodiments shown, the crosstubes extend between the right and left lower pieces of the camassembly). The cross tubes may be bent or curved, as shown. This allowsthe cross tubes to pack efficiently around the drive tube, when the baseis packed with a seat box, seat or upper furniture component.

The present invention further comprises a multi-piece cam assembly forfurniture. The figures are demonstrative and the invention contemplatesmultiple configurations including, but not limited to two, three, four,and five cam component systems.

As generally understood, ready to assemble furniture is constructed suchthat an ordinarily skilled consumer can assemble the furniture.Reclining mechanisms are typically exceedingly complex and furthermorelocking mechanisms are often excluded from ready to assemble furnitureproducts.

In one embodiment, the two-piece cam is suitable for assembling afurniture base to the seat box portion of furniture. It is furthercontemplated that the present invention is suitable for connection ofreclining mechanisms to a base in ready to assemble furniture. Recliningfurniture is without limitation and includes, but is not limited to, arocker, glider, swivel, swivel rocker, swivel glider, power variationsof all of the above, sleepers, or any piece of furniture that utilizesreclining mechanism. However, the multi-piece cam assembly is suitablefor all furniture, reclining or non-reclining, where connection isdesired, such as, but not limited to, sofas, loveseats, chairs,sectional pieces, ottomans, rockers, gliders, swivels, swivel rocker,sleepers, and the like, each with their respective seat boxes and bases.The present invention allows the seat boxes and bases to be disconnectedand connected in various combinations as desired, by the consumer, theretail store, or others, as described above.

In one embodiment, the two-piece cam is particularly well suited forconnecting a furniture frame to a base. Although the drawingsdemonstrate a first cam piece as a locking cam connected to a furnitureframe and a second or receiving cam piece connected to a base, thelocking/receiving configurations are interchangeable.

First cam piece, configured as a receiving cam 20 is constructed andarranged with a locking orifice 24. Orifice 24 is constructed andarranged to interact with locking tab 34 on locking cam piece 32.

Receiving cam piece 20 has formed thereon a horizontal support receiver22 which is constructed and arranged to receive horizontal supports 36of the present invention. In one embodiment, as seen in FIG. 1A,receiving cam piece 20 is constructed arranged with a curved lowersurface 26 that interacts with the upper surface 28 of furniture base30. In another embodiment, as seen in FIG. 1B, receiving cam piece 20 isflat and secured to base 30. In the latter embodiment, the cam piecesmay be referred to as connector pieces, i.e., receiving connector piece20 and locking connector piece 32, which combine to form a connector.

The locking cam piece 32 of the present invention is constructed andarranged to affix to the seat box or scissor/main assembly of areclining mechanism of a piece of furniture. In one embodiment, lockingcam piece 32 is affixed to the seat box. In another embodiment, the seatbox frame or recliner frame is formed with a cam portion integraltherewith. Since locking cam piece 32 is affixed to the underside of anarticle of furniture it is positioned above receiving cam piece 20whereby locking tab 34 interacts with locking tab 24 in order toremovably interconnect locking cam piece 32 with receiving cam piece 20.

Either or both of the cam pieces can in turn be provided in two or moreseparate sub-pieces. For example, in the embodiment of FIG. 1C,receiving cam pieces 20 are provided in pairs. However, locking campieces may also be provided in pairs, and either may be provided inmultiple sub-pieces.

In use, receiving cam piece 20 is positioned over a prepared uppersurface 28 of furniture base 30. When locking cam piece 32 is positionedand locked onto receiving cam piece 20 the article of furniture attachedthereto will be able to rock along base 30. Base 30 is constructed andarranged to have two main base portions each being 30 that areinterconnected by transverse supports 38. Cam piece 20 has receivingsocket 42 configured to mate with positioning tab 40 of locking campiece 32.

In one embodiment the invention is a mechanism for a piece of furniturecomprising: two or more locking cam pieces, constructed and arrangedwith at least one locking mechanism on each cam piece; two or morereceiving cam pieces, said receiving cam pieces are constructed andarranged to receive said locking mechanism, said interconnected campieces are configured to be used in reclining furniture and sleepers toinclude, but not limited to, rockers, gliders, swivels, swivel rockers,swivel gliders, twin sleepers, full sleepers, queen sleepers, kingsleepers. In addition, this mechanism assembly covers power recliningvariations.

Although a particular embodiment is demonstrated, the multi-piece cam iscontemplated to connect and disconnect in a male-female interlockarrangement. The two-piece cam represents a significant and unforeseenimprovement in furniture design and construction by providing aconstruction element that improves ease of assembly and disassembly. Themulti-piece cam assembly is suitable not only for rocking, reclining,and gliding assemblies, but for all furniture in which there is theattachment of a mechanism to a frame base. The multi cam configurationsprovide additional benefit relating to simplification of the assemblyprocess.

FIGS. 5-20 show additional exemplary embodiments of a multi-piece camassembly, comprising a receiving (i.e., a first or lower) cam piece 120and a locking (i.e., a second or upper) cam piece 130. In thisembodiment, the interlocks, 140 a, b, 142 a, b, are positioned at one orboth ends of the cam pieces, thereby providing enhanced stability whenthe cam pieces are locked together. One or more positioning elements, asdescribed below, also may be used to provide assistance in assembly andoverall stability and strength of the cam pieces when locked together toform the multi-piece cam.

An end interlock mechanism comprises one or more end tabs 140 a, bextending from the end or ends of a cam piece, and a corresponding slotor groove 142 a, b, with or without walls or tabs of its own, on theinside of the end or ends of the other cam piece, the slot or groove 142a, b adapted to receive the corresponding one or more end tabs 140 a, b.A locking tab or tabs 150 in the end interlock mechanism on one campiece engages a corresponding hole, opening, slot, groove or tab 152 inthe end interlock mechanism on the other cam piece to removably securethe one or more end tabs 140 a, b within the corresponding slot orgroove 142 a, b. To separate the cam pieces, a tool or instrument, suchas, but not limited to, a screw-driver, may be inserted into an openingin the end interlock mechanism to release the locking tab or tabs 150.In several embodiments, the end interlock mechanisms also serve aspositioning elements in addition to locking or connection elements.

While FIG. 5 shows the end tabs 140 a, b on the upper or locking campiece 130, and the receiving slots or grooves 142 a, b on the lower orreceiving cam piece 120, it should be noted that one or both end tabsmay located on the lower or receiving cam piece, and the correspondingslot or groove located on the upper or locking cam piece. Similarly, thelocking tabs 150 may be located on either the lower or receiving campiece or the upper or locking cam piece, with the corresponding hole,opening, slot, groove or tab located on the other cam piece element.

FIGS. 5-20 further show a plurality of positioning elements that may beused to assist in assembly of the multi-piece cam. One or more verticalribs, ridges or rectilinear elements 160 may be located along a side ofa cam piece, extending to the bottom or top, respectively, of the campiece, with a corresponding slot, groove or channel 162 on acorresponding side of the other cam piece element provided to receivethe corresponding vertical rib, ridge or rectilinear element 160. Thetop of the vertical ribs, ridges or rectilinear elements may be angled166 for ease of insertion. As seen in FIG. 5, the vertical rib, ridge orrectilinear extends to the bottom 122 of the lower cam piece. The bottomof the lower cam piece may be solid, or hollow in sections or parts toreduce weight.

Similarly, one or more rectilinear elements or blocks, 170 a, b, 180 a,b, 190, may be positioned along a side of the receiving or locking cam(and may be positioned along or near the top of the particular camelement), with a corresponding receiving hole or slot, 172 a, b, 182 a,b, 192, located along or in a corresponding side of the other cam pieceelement. These elements may be of substantial size, and thus provideadditional support and strength to the cam when assembled. For example,the sides of rectilinear elements 170 a, b may comprise channels 174adapted to receive corresponding tabs or ribs 176 along the inside ofthe corresponding receiving slot or hole, 172 a, b. Further, one or moreof these elements may incorporate or include one or more of thehorizontal support receivers 22.

In several embodiments, a central positioning element 190, 192 isprovided to provide additional strength and security for the assembledcam pieces. Positioning element 190 may be a simple block or flatextension, or may be L-shaped in cross-section, with a outermost element194 that latches over or slides into a groove or slot 196 in thecorresponding positioning element. This positioning element also mayserve as an additional central interlock mechanism as described above,providing three or more interlock points in conjunction with the two

In several embodiments, one or more horizontal attachment tabs orelements 200 a, b are located along or near the top of the upper campiece 130, the horizontal attachment tabs or elements comprising boltholes or slots 204 for attaching one or more mechanisms or furniturecomponents to the cam. piece. The horizontal attachment tabs 200 a, balso may comprise or be an extension of a positioning element, such asblocks 180 a, b, as described above, and fit within correspondinggrooves or channels 182 a, b in the lower cam piece 120. In theembodiment shown in FIGS. 13-20, the block positioning elements 180 a, band corresponding grooves or channels 182 a, b also may comprise anadditional tab 210 and slot or groove 212 on respective elements to helpposition and secure the respective cam pieces when connected.

As seen in several of the figures, when assembled or connected, sectionsof the top of the lower cam piece 120 are level with the top of the ofthe upper cam piece 130. Due to the nature and placement of thepositioning elements, however, in several sections the top of the uppercam piece 130 extends over the corresponding top section of the lowercam piece 120. The connected cam assembly thus provides multi-axisstrength and durability, with resistance to movement of the cam pieceswith respect to each other after connection, which can lead to breakdownor failure of one or more of the cam pieces during use.

FIGS. 21-29 show additional exemplary embodiments of a flat-sidedmulti-piece cam assembly, comprising a receiving (i.e., a first orlower) cam piece 320 and a locking (i.e., a second or upper) cam piece230. In this embodiment, the interlocks, 140 a, b, 142 a, b, arepositioned at one or both ends of the cam pieces as described above,thereby providing enhanced stability when the cam pieces are lockedtogether. One or more positioning elements, as described above, also maybe used to provide assistance in assembly and overall stability andstrength of the cam pieces when locked together to form the multi-piececam.

In this embodiment, there are no elements of either cam piece extendingoutward from the sides of either cam piece, individually or in aconjoined configuration (i.e., the sides are “flat”). Horizontalsupports are inserted into one or more cavities, orifices or openings322 in the side of a cam piece, and which may extend through some or allof the width of the cam piece. The configuration has the advantage of asimpler efficient design without exposing any extended elements todamage or breakage during shipping or assembly.

Fastening means, such as a hole 312 a, b, on the interior of the orifice322 may be used to receive a spring-based tab or extension element onthe horizontal support to hold the horizontal support securely in place.The fastening means can be released by pushing the tab or extension downor inwards. In other embodiments, the horizontal support may comprise ahole extending therethrough proximate to the end, and configured toalign with matching holes 310 a, b extending vertically through the campiece and opening into the corresponding orifices 322. A screw or boltmay then be inserted into the holes 310 a, b and through thecorresponding holes in the horizontal support when inserted into theorifice.

The embodiments shown in FIGS. 5-29 also possess a significant advantagein shipping of the respective furniture pieces or components with therespective cam pieces attached, as it has no positioning elementsextending outward from the top or bottom of the respective cam pieces orcomponents, or, in the case of FIGS. 21-29, from the sides of therespective cam pieces or components. For example, a positioning tab orelement extending from the bottom of the upper or locking cam piece canbe damaged or bent during shipping, thereby interfering or preventingthe proper functioning of the cam elements and assembly.
